Daytime Running Lamps Daytime Running Lamps (DRL) can make it easier for others to see the front of your vehicle during the day. DRL can be helpful in many different driving conditions, but they can be especially helpful in the short periods afterdawn and before sunset. A light sensor on top of the instrument panel makes the DRL work, so be sure it isn't covered. The DIU system will make your high and low-beam headlamps come on at a reduced brightness when: The ignition is on, The headlamp switch is off, and The parking brake is released (manual transaxle); or The transaxle is not in PARK (P) or NEUTRAL (N) (automatic transaxle). When the DRL are on, only your high and low-beam headlamps will be on. The taillamps, sidemarker and other lamps won't be on.Your instrument panel won't be lit up either. When it's dark enoughoutside, your headlamps will come on at full brightness.The other lamps that come on with your headlamps willalso come on. When it's bright enough outside, the regular lamps will go off, and your high and low-beam headlamps change to the reduced brightnessof DRL. To idle your vehicle with the DRL off, set the parking brake on a manual transaxle or put the vehicle in PARK (P) or NEUTRAL (N) on an automatic transaxle, while the ignitionis in the OFF or LOCK position. Then start the vehicle.The DRL will stay off until you release the parking brakeon a manual transaxleor shift out of PARK (P) or NEUTRAL (N) on an automatic transaxle. As with any vehicle, you should turn on the regular headlamp system when you need it.
